Reading specs from 
/opt/net/local/gcc2953/lib/gcc-lib/sparc-sun-solaris2.6/2.95.3/specs
gcc version 2.95.3 20010315 (TWW)

-----------------------------------------


To recreate the problem is easy, which  is unusual. Using the sample.c program 
in the ddd manual, attached.

compile it and run it with, 

$ gcc -g -o sample sample.c
$ ddd gcc 8000 7000 5000 1000 4000

put a breakpoint on the line a = (int *)malloc((.......
use the run option and when the execution stops, then one single step

Now use the menu option data->memory...

set examine to 16 and select hex, and enter the address of the variable 'a'.

I got the address by hovering the cursor over the 'a' in the line you have the 
break point on.
